教学目标 Course Objectives

本课程主要为数学系数学与应用数学专业设计，分成 I、II 两部分，按两个学期连贯教学。课程旨在引导学生深入系统地学

习该专业所需要的代数学基本知识，为数学专业高年级的后续课程打下扎实的基础。课程内容将按照高于同类课程的标准

进行教学和考核，以培养出代数学基础最扎实的学生为目标。

本课程(高等代数 II )内容主要包括：双线性型和内积空间，多项式分解及其应用，线性算子的谱理论，Jordan 标准形，欧

氏空间的旋转变换群，以及若干选讲专题。

This course is primarily designed for students majored in pure and applied mathematics, and is divided into Parts I and II,

lasting ideally for two consecutive semesters. It aims at leading students into systematic and thorough studies of the

fundamentals of modern algebra, thus getting them to lay a solid foundation for subsequent, more advanced courses in

math major. The contents of the course and the standards of assessment will normally surpass the other courses in the

same series, the objective being to foster students with best background in algebra.

Main topics of this course (Advanced Linear Algebra II) include：Bilinear forms and inner product spaces, polynomial

factorization and applications, spectral theory of linear operators, Jordan canonical forms, rotation group of Euclidean

spaces, and some selected topics.

预达学习成果 Learning Outcomes

通过对本课程的学习，学生能够理解和掌握高等代数的更深入理论(包括内积空间、若当标准形、正规算子、谱定理等)和

在一些重要应用。同时，学生应当逐渐培养出较好的抽象思维能力和进行严密数学推理和证明的能力。

An adequate training through this course should help the students to understand the basics of advanced linear algebra

(such as inner product spaces, Jordan canonical forms, normal operators, spectral theorems) as well as some important

applications. Also, students are expected to gradually foster the ability of abstract thinking and doing logically rigorous

arguments and proofs in math.
